Specication of Letters Patent. Patented ADI. 11, 191 1.

Application. tiled April 21, 1910. Serial No. 556,840.

To all whom it may concern l Be it'known that I, Gns'rAv SCHWAB, asubject of the Emperor of Germany, residing at Chicago, in the county'of Cook and State ot Illinois, have invented a new and usefulimprovement in Coke-Ovens, of which the following is a specification.

My invention relates particularly to ovens adapted to produce coke fromcoal; and my 1i) primary object is to provide an improved oven-structureinvolving the use of improved heatingtlue construction between theseries of ovens employed in the structure, whereby .the heat employedfor coking purposes may be more effectively and more completelyutilized, whereby the oven-structure will be less liable to injuriousell'ccts .from contraction and expansion, the life o't the structurewill be lengthened, and, in genso eral, coke may be produced morecconomt cally than in ovens ot' known construction. The invention alsorenders it possible to construct the ovens ot' any desired 'size withoutnecessitating special reinforcement, und Without loss of economy inoperation.

The invention involves, in the form illustratcd, a construction whereinare employed a series ot ovens Whose lateral walls are formed. byspecially constructed vertically disposed heating tlues so designed asto connnunicate heat to the ovens in the most. ellicient manner and towithstand etl'ectivcly the contraction and expansion incident to thereversal of the course of thc products ot combustion usual in an ovenot' the regenerative type.

The invention is illustrated in the pret'erred embodiment in theaccompanying drawings in which- Figure 1 represents a broken sectionalView of an oven constructed in accordance with my invention, the sectionbeing taken parallel with one side or t'ront ot the oven, 'as indicatedat line 1 of Fig. 2; Fig. a transverse section taken as indicated atline i? of Fig. l, the section cutting one oi:l the oven chambers; Fig.2l, a broken longitu- `dinal section taken approximately :ns indi? catedat line -3 ot' Figs. 2 andl, thc section at the upper portion ot thefigure boing taken on a stepped liuc, as indicated by the broke-n walls,the purpose bcing to show thc inspcctitm openings through thc upperValls o't"`the structure as well as the charging openings thcretlnough;Fig. 3, a broken section on an enlarged scale, showing .the flueconstruction, the section being taltcn as indicated on line il ot Fig.(t: Fig. 1t, a transverse section taken as indicated at line Lt of Fig.3, this section passing through a vertical flue series separatingntwoovens; Fig. 5, a broken'horizontal section, taken. as indicated, on line5 ot Fig. it; Fig. G, u broken plan view showing a fragment ot' the flueconstruction.

ln the construction illustrated, the ovcnstructure comprises a base wall1 and lateral walls 2 and Q; a series of ovens 3 having openings 4Cthrough said lateral walls; a vertical .[tuc. serios 5 between each twoadjacent ovens and forming the lateral walls of said ovens; longitudinalgas mains T at euch side or front of the coke-oven structure, from cachot which rises a Series of gas pipes 8, and a series oit' gas pipes Sadmitted to be alternately used, said gas pipes being controlled,respectively, by gas cocks 9 and tl; a laterally `disposed chamber 10'Ior cach gas main `and the gas pipes rising there from; a pair oflongitudinally extending main conduits 11 and 11 which extend throughthe base of thc structure and are locntednear the sides of thcstructure, and which servealternately as air admission and combustionproducts outlet conduits; a series ot transversely extending rcgcncratorconduits 12 located in the base 1, ol the structure beneath alternateones ot the ovens 3. and connnunicating with `the main conduit l1 aseries oi" similar regenerator couduits or, chambers 12 located beneaththc. remaining alternate ovens and communicnting with thc main conduit'1l; a series ot comluits` 13 connecting thc conduits 12 with the mainor loi'igitudinul conduit 11; u series o't' conduits 125 ctmnccting theconduits 12 with thc longitudinal conduit 11:

vulves 13" controlling the conduits lil. and valves 151" controlling'the ctmduits ilzlr; n series ot comparatively small conduitsl 'lf-tdisposed just beneath the bottoms ot the ovens and above the conduits orregenerative clutmbcrs 12; a series o't alternating conduits istdisposed above` the rcgcmrutirc conduits 12 und beneath the bottoms ot'the corrcspomling ovens; passages 15 through which the conduits 12 arein communication with the conduits 1.4; passages 15 through which-theconduits 12 are in communicaY tion with the conduits 14; two seriesoliintit , inspected..

clined passages 16 through` which the con-,

duits 14 communicate` with alternate Vertical lues oi"l the two flankingheating iiue series, and 'two series of inclined passagesV 16a throughwhich the conduits 141il communicate ,with alternating'vertical heatingiiues of the two tlankin heating flue series. l

Gdn'erally speaking, the Walls of the cokeo'v'en" structure are composedof brick, butv any-suitable material may be employed. As shown, the baseWall l has, in itsl'ateralsurfaces, openings 17, through Which, in Fig.1, may be viewed the .Walls of the conduit 11, and the view-openings 6leading to conduits 12 and 12a. in practice,'the openings 4, at the endsoi' the ovens, are closed by doors (not shown). Through the upperWall'f" the structure extend charging openings 18 leading to the ovensand vent` openings 19 communicating with the oyens;` also view openings20 enabling the Vvertical lines to be Each flue seriesis preferablyconstructed in themanne'r vshown inlqdetail :ln-Figs. 3f, 5, 6. As thusconstructed," each flue series is provided with ayerticalseriesof lfines21 which, in pairs,=`alterna'te Withthe pairs of a vertical seriesoftlues l22. The-,Hue construc` tion is such that eachfluehas:triangular verticai Walls, andv the referred manner of securing suchtriangu a1' walls is to construct two substantially` parallel walls 23which are joined by oblique walls 24. The

oblique Walls 24 and the parallel walls 23, in

part, are formedl by``4` means, of Y-shaped bricks having a stemor'bas'e25 and arms 26. In laying the .Wa-11s, the "stems or base ortions 25 alternate .with 'simple or straight bricks 27 at one Wa11023,While the entremities of the arms abut against simple or straight bricks27 in the opposing Wall 23.l In the next course, the stems or basertions 25 are laid as a part-of the other Wal 2,3, beJ linnr placed sothat ythe base 'portions'o'f-the 45' arms projecting from eachfstem'willlie over the free end portions of thearms ,of thelni-l derlying courseof Y-shaped bricks. As thus constructed, the Y-sha-ped bricks vareirmlyubound together and also bound to the par-:

allel Walls, it being understood that the Y;l

shaped bricks of one course bear Whatmayv be termed a. staggeredrelation to the vY- shaped bricks of the next course. ,The iues 21communicate through 'the assages 16 with the conduits 14, and the ues 22conimunicate through the passages I6 with "the conduits 14.

' Each. vertical gas pipe 8 is provided l.with a pair of inturnedbranches 29, and 30 which communicate with channels or gas passages 31and'32 respectively. The channels-3l are disposed directly beneath theheating iiucs and extend inwardly from the lateral surfaces of thestructure y.appronimately` onequarterof the distance across; and thepasthe spaces sagen 32' communicate with channels 33 which are separatedfrom each other-,1 by a Wall 34 and fromthe channels 31 bylwalls Thechannels 31 and 33 communicate with the vertical heating dues 21 throughinclined passages 36. The gas pipes 8a coinmunicatc through branches 29aand 30 with passages 31a and 32 similar to the passages 31- and 32 andlying close beside them, the passages 32a communicating with passages 33which lie side by side with the passages 33 and are similar thereto. Thepassages 31 and 33 communicate through inclined pasl sages 36a with thevertical iiues 22. K The operation will be readily understood from theforegloing detailed description. We may assume t e conduit llto beplaced in' communication with the smokel stack or chimney and theconduit 11 to be placed in communication With the atmosphere 'by theusual means (not shown) As 4thus arranged, 'assuming the valves 9controlling the u'erticafl gaj'sjjpipes 8 to be opened, as by means of achain 37 gas will be supplied to the channels 31 and 33, whence itwilllpass through the passages 36 to the vertical heating fines.` 21. Atthe same time air Will be drawnf throu h the longitudinal conduit 11 andcross conduits 12, whence it will pass through the passa" S15 to thesmaller cross conduits 14+. and t ence through the inclined passages 16to the vertical flues 21, Where it will unite with the as'to form theprodilcts'of combustion,.the urning gases then passing through 38 at theupper ends of the Walls separating the fines-21 from ,the lues52'2, as`indicated in Figi-4, thence down through the fines 22, the passages'16?, the small cross y conduits 14, and the passages 15 to the .larera'cross conduits or regenerators 12a,- an thence to the longitudinalconduit 11' vwhich is in4 communication with the chimhey. After' oeration in this manner for a 'predeterminedp' eriod, the operation isre- `versed, the longltudinal conduitll 'is placed in communicationwiththe chimney and thc -conduit 11a is placed in communication with ltheatr1'1os1: here. The as cocks 9 are then lclosed and the gas cocsQopened, Whereupon the combustion begins in the' vertical flues 22 and iscontinued by a down draitl through the flues 21, the outlet beingthrough the inclined passages 16, the small cross conduits 14, thepassages 15, the large cross conduits or regenerators 12 and finallythrough 120 the longitudinal'conduit 11 to the chimney.

It will be noted that by reason of my im proved flue construction theheat is evenly distributed to the ovens ankingtheiiiie v series, theilues are soarranged as to enable expansion and contraction to occurwithout injurious results, the Walls being mutuallybracing, andythe'most eiicient use is made of thehcat units generated by theburning'.A gases. j

` derstood therefrom,

lVhile the invention -is illustrated in connection with a coke-ovenemploying vertical heating fines and horizontal ovens, it will,`

ings 39 which are in alinement with view openings 39a 1n the alternatingwall extensions 40 at the upper ends of, the tlues. View openings 41extend through the upper walls Ll2 which cap the fine series, the viewopenings 41 communicating with the enlarged openings or chambers 20shown in Fig. 3 and which have heretofore been mentioned. The chambers20 are covered by removable plates 43 giving access to the longitudinalchambers 20, The View openings 3S) are ordinarily closed and theopenings 39 are too small to interfere with the draft of the heatingfines, but are large enough to enable the operation to be viewed. Theview-openings 41 are covered by removable bricks 43.

The foregoing detailed description has been given for .clearness ofunderstanding only, and no undue limitation should be unbut the appendedclaims should be constructed as broadly as permissible in view of the]prior art.
